Yang Kai finds a book that rewrites the rules of cultivation, and from that moment forward every enemy he faces is either a stepping stone or a lesson in survival that costs him something real. The power progression doesn't feel like numbers going up, it feels like a person learning to push past their own breaking point, over and over. This is xianxia that remembers that the loneliest martial path is the one nobody else can walk for you.

Yang Kai holds the lowly rank of trial disciple at the Lingxiao sect, where he also sweeps the floors. His weak aptitude cost him his standing, and unless he proves himself within three years he will be thrown out. His fortunes change when he stumbles upon a mysterious object, described as a wordless black book, that unlocks secret techniques. Driven by stubborn resolve, he trains to break through his own limits and set out on the long climb toward the summit of martial arts. The ONA mixes action, adventure and fantasy with a thread of romance.
